Description Henk Jan Priester 2010-09-15 16:24:39 UTC 
When rasterizing a large PDF with transparancy using the following commandline:

time $GS_DIR/bin/gs -dNOPAUSE -dBATCH -dBufferSpace=50000000 -r600 -sDEVICE=png16m -sOutputFile=strike.png strikeline1.pdf

GhostScript 9.00rc3 is very slow compared to 8.70. (113 vs 8.5 minutes)
